I have a passage in my game, where the player has to decide within a few seconds. The problem is: Forcing a player to make a decision without "pressure" isn't fun. Now my question is: Is it possible to show a counter and jump to the next passage automatically?

Example:

The player has 20 seconds to decide if he wants to go the left or the right way. After this 20 seconds the player automatically goes the left way. The counter should be visible all the time, so the player knows he has to decide fast.
